Junger was born in Belmont, Massachusetts, the son of Ellen Sinclair, a painter, and Miguel Chapero Junger, a physicist.[4][5] His father was born in Dresden, Germany, of Russian, Austrian, Spanish, and Italian descent; he came to the United States during World War II because his own father had been Jewish.[4][6] Junger grew up in the neighborhood of the Boston Strangler, a circumstance that later inspired his 2006 book A Death in Belmont.[5]

He found fame after writing the international bestseller The Perfect Storm: A True Story of Men Against the Sea. Published in 1997, it recounts the tale of the October 1991 "perfect storm" (in fact, the general use of the term originates from this book), focusing on the loss of the Gloucester fishing boat Andrea Gail off the coast of Nova Scotia and its six crew members, Billy Tyne, Bobby Shatford, Alfred Pierre, David Sullivan, Michael Moran and Dale Murphy.[20]

At the time of the storm, Junger was recovering from a wound to the left leg that he suffered while working as an arborist in the Boston area (his chainsaw had torn into his leg).[21] He claims that while recovering from that injury, he was inspired to write about dangerous jobs. He planned to start with commercial fishing in Gloucester Mass. which evolved into "The Perfect Storm".[22]

Junger established The Perfect Storm Foundation to provide cultural and educational grants to children across the country whose parents make their living in the commercial fishing industry.[23]

A Death in Belmont centers on the rape-murder of Bessie Goldberg in Junger's hometown in the spring of 1963. From 1962–1964, the Boston area was gripped with fear as a result of the infamous Boston Strangler crimes. Junger received the 2007 PEN/Winship award for the book.[24] Although a different man was convicted, Junger raises the possibility that the real killer was Albert DeSalvo, who eventually confessed to committing several Strangler murders, but not Goldberg's. Goldberg's house was a mile and a quarter from the Junger family home, where Albert DeSalvo was doing construction work on the day Goldberg was killed. In fact, Junger stated in an interview that he grew up with a studio portrait of DeSalvo on his family's wall.[25]

The book includes a photograph that was taken one day after Goldberg's murder. It shows Junger as a one-year-old baby, sitting on his mother's lap; They are in the new room that had just been added onto their house, and standing behind them are the two contractors who had just completed its construction. Junger describes it thus:

"Al and I are the only people looking directly at the camera, and whereas I have an infant's expression of puzzled amazement, Al wears an odd smirk. His dark hair is greased up in a pampadour, and he is clean-shaven but unmistakably rough looking, and he has placed across his stomach one enormous, outstretched hand. ... The hand is at the exact center of the photograph, as if it were the true subject around which the rest of have been arranged."

Junger's book raises the possibility that Smith's conviction was founded on circumstantial evidence, and in part on racism, because the prosecution's narrative of Smith's day in Belmont was built on witnesses who remembered seeing Smith chiefly because he was a black man walking in a white neighborhood. Smith had cleaned the victim's house on the day in question and left a receipt (for his work) with his name on the victim's kitchen counter. There was no physical evidence, such as bruises or blood, linking Smith to the crime. In 1976, he was granted commutation of his life sentence; however, before his release, Smith died of lung cancer.[27][28][29][30][31]

In his final analysis in A Death in Belmont, Junger draws no conclusions about the guilt or innocence of Smith or DeSalvo. The victim's daughter has vigorously disputed Junger's suggestion that Smith might have been innocent.[28]

Fire is a collection of articles dealing with dangerous regions of the world or dangerous occupations. It is most notable for its chapter "Lion in Winter" in which Junger interviews Afghan Northern Alliance leader Ahmad Shah Massoud, the Lion of the Panjshir, a famed resistance fighter against first the Soviets and then the Taliban. Junger was one of the last Western journalists to interview Massoud in depth. The bulk of this interview was first published in March 2001 for National Geographic Adventure,[32] along with photographs by the renowned Iranian photographer Reza Deghati and video by cinematographer Stephen Cocklin.[33][34][35][36] Massoud was assassinated on September 9, 2001. Junger's portrait of Massoud gives one insight into how differently Afghanistan might have fared in the post-9/11 invasion had Massoud lived to help reclaim the country from the Taliban. Fire also details the conflict diamond trade in Sierra Leone, genocide in Kosovo and the hazards of fire-fighting in the Idaho wild.

In 2009, Junger made his first film, the documentary feature Restrepo, as director with photographer Tim Hetherington. The two worked together in Afghanistan on assignment for Vanity Fair. Junger and Hetherington spent a year with one platoon in the Korengal Valley, which is billed as the deadliest valley in Afghanistan. They recorded video to document their experience, and this footage went on to form the basis for Restrepo. The title refers to the outpost where Junger was embedded, which was named after a combat medic, Pfc. Juan Restrepo, killed in action. As Junger explained, "It's a completely apolitical film. We wanted to give viewers the experience of being in combat with soldiers, and so our cameras never leave their side. There are no interviews with generals; there is no moral or political analysis. It is a purely experiential film."[37]Restrepo, which premiered on the opening night of the 2010 Sundance Film Festival,[38] won the grand jury prize for a domestic documentary. The actor David Hyde Pierce presented the award in Park City, Utah.[39] Junger self-financed the film.[40]Restrepo was nominated for the 2011 Academy Award for Best Documentary.[41]

The visits from June 2007 to June 2008 to eastern Afghanistan to the Korengal Valley with Tim Hetherington resulted not only in their reports and pictures published in Vanity Fair in 2008 and the film Restrepo (2010), but also in Junger's best-selling book War (2010),[3] which rewrites and expands upon his Vanity Fair dispatches.[42][43]Time magazine named War a "Top Ten Non-fiction Book" of 2010.[44]

Junger speaking at the LBJ Library, which screened Which Way is the Front Line From Here?

In April 2013, Junger's film Which Way is the Front Line From Here? The Life and Time of Tim Hetherington, debuted at the LBJ Presidential Library. Produced in conjunction with HBO Documentary Films, it documents the life of Tim Hetherington, focusing upon his documenting the humanity of people caught up in war.

The 2014 film Korengal continues to follow the soldiers in Battle Company 2/503 during and after their service in the Korengal Valley.[45] The film takes a deeper look into the psychology of the men, who are deployed in the rugged mountains of the Korengal Valley. Junger sought to find out what combat did to, and for them, and seek a deeper understanding of why war is meaningful to them. [46] The film opened in June 2013 in theaters. It also played at the Pritzker Military Library and Museum, The Pentagon, Army Heritage and Education Foundation Center, Capitol Hill, United States Military Academy, The National Infantry Museum, Little Rock Film Festival, Key West Film Festival, and the DocuWest Film Festival. [47]

The last of the trilogy about war and its effects on soldiers, this documentary explores "what it means for combat soldiers to reintegrate into daily American life."[48] Junger recruited former US Army Sgt. Brendan O'Bryne, who appeared in the film "Restrepo," US Army soldier Dave Roels, and Spanish photo-journalist Guillermo Cervera to walk the rail corridor between Washington, D.C., Philadelphia, and Pittsburgh. The journey was planned as a tribute to deceased photographer Tim Hetherington.[49][50] The film premiered at the Margaret Mead Film Festival [51] and aired on HBO in November. The film played in theaters in NY, and Los Angeles, as well as at the Savannah Film Festival, and at SIFF in Seattle. [52][53]
